KODIAK, Alaska (AP) -- Police in Kodiak are asking people to keep an eye out for a missing explosive.

Police say a fluorescent-green plastic cylinder containing an explosive was taken Thursday morning from a quarry on Near Island. The cylinder is about 4 inches by 2 inches with a cord protruding from one end.

The explosive disappeared between 10 a.m. and noon. Police say it likely was removed from a hole bored in a rock wall.

Adolescents were seen walking through the area.

Police Chief T.C. Kamai says the explosive was not connected to a detonator but they're asking people not to touch it.
